Renkforce Jumper Cable JKMM406 — 40-wire bridge set for PCB and prototyping

Renkforce Jumper Cable JKMM406 is a set of 40 individual wires for PCB connections and electronic prototyping. Each wire is intended for linking headers, modules and test points on development boards such as Arduino, Raspberry Pi and Banana Pi. The flexible jumper set supports rapid circuit changes, breadboarding and signal routing during assembly, testing and repair.

Advantages

The 40-wire bridge set provides many separate conductors in a compact package, enabling neat and reliable temporary or semi-permanent connections. Wires are color-coded for easier identification and organization. The jumper cables are compatible with common single‑row and multi‑row headers used on microcontroller and single‑board computer projects.

Suitable for

• Prototyping on breadboards and development boards
• Connecting headers, modules and sensors to Arduino, Raspberry Pi, Banana Pi
• Signal routing and temporary wiring during testing and repair

How to use

Choose wires of appropriate length and insert the connectors onto the target header pins, module pins or test points. Use the color coding to keep track of signals and routes. For breadboard use, push the wire ends into the breadboard holes or header sockets until they seat firmly. Remove or reposition wires as needed during iterative prototyping and testing.

Usage recommendations

Use the jumper cables for low-voltage signal and prototype connections only. Avoid excessive mechanical stress on soldered joints and connector pins. For permanent or high-current connections, use appropriately rated cables and soldered or crimped terminals.
